根据苏联[焊接生产]杂志1959年1期,我们把ПШ-5型半自动电焊机改装为电铆焊机,不仅给半自动焊机更广泛的利用开辟了新的途径,同时在工业生产上也有重大的价值。它比手工电铆焊大约提高3～4倍工作效率。因为半自动焊使用的电流大,熔化深度大,一般3～4毫米的板料不要开槽或钻孔,就可在上面熔透,形成熔化电铆接头,所以简化了产品加工工序。熔剂层下 According to Soviet Union [Welding Production] magazine 1, 1959, we converted the semi-automatic welding machine Ш-5 into an electric welding machine, which not only opened up a new way for the wider utilization of semi-automatic welding machine but also made great achievements in industrial production the value of. It is about 3 to 4 times more efficient than manual power welding. Because semi-automatic welding using large current, melting depth, the general 3 to 4 mm of the sheet do not groove or drill, you can melt in the above, the formation of molten riveting joints, thus simplifying the product processing processes.
